What is disulfide bond cleavage?
Disulfide bond cleavage is a chemical change that leads to an alteration of the cuticle cells, increased porosity and a roughening of the hair’s surface. This results in increased combing forces, a loss in mechanical strength, increased damage from UV exposure and in turn breakage of the hair. This weakening of the hair shaft causes loss of color and tonality as well as increased breakage. The tryptobond guardä in Therapy-G shows over 90% increased disulfide bond protection.
